Waste fruit peels which are usually discarded as agricultural wastes were utilized to isolate cellulose. The varied amount of isolated cellulose was used as sustainable support with hydrothermally synthesized molybdenum sulphide (MoS) nano-petals via in-situ approach. The phase purity of all synthesized nanostructures was confirmed by PXRD whereas different oxidation states along with the interaction of cellulose with the MoS were examined by XPS analysis. In order to evaluate the performance of catalyst, the photodegradation rate was calculated for RhB dye as well as industrial effluent in visible light. The upgradation in photocatalytic competence was found significant by cellulose supported MoS nanostructures as compared to bare MoS nano-petals due to slow recombination of electron hole pairs. The maximum rate was pronounced by employing the cellulose at an amount of ~500 mg as a support due to existence of an optimal point where the delay in charge recombination reaches maximum.
废弃果皮通常作为农业废弃物丢弃,现被用于分离纤维素。通过原位法,将不同量的分离纤维素用作水热合成二硫化钼(MoS)纳米花瓣的可持续支撑物。所有合成纳米结构的物相纯度均通过 PXRD 确认,而 XPS 分析则检查了纤维素与 MoS 的不同氧化态和相互作用。为了评估催化剂的性能,计算了 RhB 染料和可见光下工业废水的光降解率。与裸 MoS 纳米花瓣相比,纤维素负载 MoS 纳米结构的光催化性能得到了显著提升,因为电子空穴对的复合速率较慢。通过使用约 500mg 的纤维素作为支撑物,可以获得最大的光降解速率,因为存在一个最佳点,在该点处,电荷复合延迟达到最大值。
